ABSTRACT Weed control is one of the most difficult tasks on an agricultural farm. Three methods of weed control are commonly known in agriculture. These are mechanical, chemical and biological control. Mechanical weed control is easily adopted by farmers once they get convinced of its advantages. Mechanical weed control not only uproots the weed between the crop rows but also keeps the soil surface loose, ensuring better soil aeration and water intake capacity. Weeding by mechanical devices...
ABSTRACT Drying is the oldest method of preserving agricultural products and it is an energy intensive process. High prices ·and shortages of fossil fuels have increased the emphasis on using alternative renewable energy resources. Drying of agricultural products using renewable energy such as solar energy is environmental friendly and has little environmental impact. Development of solar drying has brought a techniques and equipment for fast drying of various agricultural product foods...

ABSTRACT Most organizations are deploying e-business solutions because of its numerous advantages, such as, increased productivity, reduced transactions costs, wider coverage and increased speed to market. The present academic offices in developing countries still use paper-based approach for most of their activities. Data and information are logged into files, folders and excel sheets which are printed, bound and saved into drawers that are rarely used again for other purposes. In the un...
ABSTRACT The purpose of this work is to use the energy approach in the form of direct variational principle (Rayleigh-Ritz method) for buckling analysis of thin rectangular plates with various boundary conditions using Taylor series shape functions. To do this, thin rectangular flat plate of various boundary conditions with three dimensions Ly, Lx and t was analyzed in this research. Ly and Lx are secondary and primary in-plane dimensions respectively and t is the plate thickness. The bou...
Abstract The aim of this work is to characterize properties and microstructure of stainless steel used as a coating on welding of carbon steel sheets. Two carbon steel plates were set as the metal base and the stainless steel coating was applied on the weld bead. The applied process used was the submerged arc welding (SAW) and tests were carried out for the tensile strength and Vickers hardness, in addition to observation of the microstructure by optical microscopy. The results indicated that...
ABSTRACT This project shows the construction of a microcontroller based security door using Smart card. It is aimed towards programming the microcontroller to control the Hardware in sliding door. The system consists of a microcontroller 89S52 which Sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the Card user in the liquid crystal display (LCD). The LCD displays the status of th...
Abstract My project is to improve JIT store management system from manual to automated system. Which is used to avoid problem faced by store keeper when store material manually. Store is the place where many varieties of materials are kept for the purpose of work. So at a time of storage is hard to write in document all material listing by their name, id, model, price and quantity; and is also boring to search specific material from whole material for human being but is easy for computer ...
ABSTRACT This work investigated the variation of top loss heat transfer coefficient with the emittance of the absorber plate, the collector tilt angle and air gap spacing between the absorber plate and the cover plate. The effects of the emittance of the absorber plate, the collector tilt angle and air gap spacing between the plate and the cover on the collector performance were also considered. Data collected from the thermosyphon solar water heater constructed by the National Centre for En...
ABSTRACT Sugarcane as an agricultural product is a readily available source of food for its sugar content. However, Sugarcane Bagasse Ash (SCBA) is the bi- product formed at sugar industries from the burning of sugarcane after the sugar content has been extracted. Sugarcane Bagasse Ash (SCBA) is a fibrous waste product containing mainly aluminum and silica, calcium ions to produce calcium aluminate hydrate (CAH) and calcium silicate hydrate (CSH) shown in the pozzolanic reaction below. Ca2+ +...
ABSTRACT This project involves the design and implementation of an intelligent obstacle-avoiding robot car. The objective of this project is to implement a robot car, which while moving should have the ability to detect obstacles in its path and change direction where obstacles are present without any form of external influence. The new direction to be taken to avoid collision is the direction that has the most distance between the obstacle and the sensor and this is determined by the robot b...
ABSTRACT When comparing with other manufacturing technologies, the extrusion technology always stands out as it is known to be highly efficient in terms of producing products of superior quality with the least possible amount of wastage. With the ever-increasing cost of materials, energy and the competition in the market, it becomes almost necessary to device a model with the minimum number of trials and shortest lead time. A multi-hole extrusion process was hence devised to serve the above n...
Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not azeotrope in the binary mixture, but sometimes there are components which do azeotrope despite having vastly different boiling points. It is likely that in ...
This project study was aimed at designing, fabricating, and evaluating the performance of a double effect evaporator, which was used to evaporate sugar syrup to be used for students’ demonstration. During the course of the study, the methods that were used comprised of the material balances, energy balances, and determination of the component parts of the evaporator. The results from the study included the overall material in the evaporator’s system, the material balance for each effect, ...
ABSTRACT The sandcrete blocks have been a major material for the construction of structures in Nigeria. This material have provided a means of constructing walls and partition. However, the sandcrete blocks also have the disadvantage of cost and unavailability of materials such as granite, cement and other combining aggregates. Laterite, a readily available material can be efficiently used to produce Laterite bricks which can be fired to improve it's mechanical and physical property. The inc...
